These economical stirring hot plates feature a soft start motor to prevent samples from splashing and spraying. Stirrers produce a strong magnetic field to create speeds that are adjustable from 50 to 2000 rpm. The composite stainless steel plate ensures rapid heat up to the desired temperature up to 608°F (320°C). Produce highly accurate temperature control by connecting stirring hot plates to an external sensor according to DIN 12878. An indicator warns when the plate is hot to prevent burns.
